consult your CLARKE dealer.
4. Make sure that the jack is on a hard level surface, and there is no possibility
of it slipping when under load.
5. Make sure the load is taken by the full saddle and that the lifting point on
the load, is of sufficient strength to support the weight.
6. Always use axle stands to stabilise the load once lifted.
7. NEVER work on or under a load unless it is fully and adequately supported.
NEVER rely upon the jack to hold the load in position.
8. Never push a load off the jack.
9. Ensure that all personnel are well clear of a load being raised or lowered.

OPERATION
POSITIONING
Ensure the vehicle is chocked and stable and on firm level ground.
1. Turn the jack handle counterclockwise, to lower the lifting ram.
2. Position the jack so that the saddle is directly beneath the lifting point and
that there are no obstacles to prevent a clean lift, also, make sure that all
personnel are well away from the area, before raising the vehicle.
TO LIFT
1. Close the release valve by turning the jack handle clockwise firmly.
2. Operate the jack by pumping the jack handle.
• Make sure that the saddle is in full contact with the vehicle lifting
point and that there are no obstacles to prevent a clean lift.
3. Place axle stands beneath the vehicle.
• Make sure that the axle stands are centred under the vehicle
support points and are perfectly stable before full weight is taken.
• Make sure that that the axle stands are in good condition and
capable of supporting the load.
• Make sure that the axle stands cannot move when supporting the
load and that they are on a firm level surface.
• DO NOT jerk the handle, ensure it lowers slowly and under complete
control on to the axle stands which must be correctly positioned and
take the weight evenly.
TO LOWER
1. Lift the vehicle slightly to remove the weight from any supports.
2. Remove any supports from beneath the vehicle.
3. Slowly turn the jack handle counterclockwise to open the release valve.
NOTE: make sure that this operation is carried out under complete
control. Do not allow the load to drop suddenly as this could
damage internal components.
4. Remove the jack from beneath the vehicle.
NOTE: The jack may move slightly during operation. It is therefore
important that the immediate vicinity is clean and completely
free from clutter.
